Ventilation and heat dissipation method for factory building
The invention relates to a plant ventilation and heat dissipation method which mainly comprises the following steps: a plant overall parameter design step: theoretically estimating and adjusting the required total air volume, the total window area, the window air outlet speed and the indoor and outdoor pressure difference; a geometric design step of an air outlet pipeline: performing preliminary design according to the basic principle of fluid mechanics, and then calculating and designing the geometric size of the pipeline according to a computer program so as to enable the maximum air speed or flow unevenness of each air outlet to reach a satisfactory low value; a workshop pipeline position configuration design step: estimating and adjusting a flow field, a temperature field and a concentration field in a workshop by using a computer program so as to adjust the horizontal installation position and height of the pipeline and the height of a window, so that the wind speed, the temperature and the concentration in the workshop reach required values; and the temperature and the pollutant concentration in the plant are reduced.
本申请涉及一种厂房通风散热方法，一种厂房通风散热方法主要包括下列步骤：厂房整体参数设计步骤，其以理论估算并调整需求总风量、窗户总面积、窗户出气速度、室内外压差；出气管道几何设计步骤，其先以流体力学基本原理做初步设计，再以计算机程序计算，设计管道几何尺寸，以使各出风口最大风速或流量不均匀度达到满意的低值；以及厂房管道位置配置设计步骤，其以计算机程序估算并调整厂房内流场、温度场、浓度场，用于调整管道安装水平位置、高度与窗户高度，以使厂房内的风速、温度、浓度达到要求的数值：用于阻挡粉尘飘入厂房内，并降低厂房内的温度与污染物浓度。
